What is a flames?

Answer 1

A flame is a chemical reaction between two or more chemicals that produces heat and light and other chemicals, (products of combustion), For a constant flame to be maintained then there must be a method of renewing the supply of the two or more chemicals. (usually convection)

A typical example of a flame, is a candle. This is usually a rod of wax with a central wick, the wick is ignited, heat from the flame at the wick melts the wax the now liquid wax is absorbed by the wick, and through capillary action the wax (fuel) is a fed to the flame. The heat from the flame causes a column of hot gases to rise Upwards and away from the candle, thus removing the product of combustion from the area and drawing in a fresh supply of oxygen which combines with the fuel in the flame to produce more heat, continuing the process.

In internet usage, a flame is a insult, usually lengthy, about what a user has posted and generally doesn't hold any real information.

Commentary

I like this question because of this interesting fact I discovered recently. A match will not burn in zero gravity. Experiments with matches on the space station showed that they extinguished themselves shortly after ignition because the gases produced by the combustion remain around the flame, cutting off the oxygen supply to the flame thus extinguishing it.
